title: [Conical amputation of the cervix with CO2 laser (author's transl)].
abstract: Conical amputation of the cervix is performed to treat intra-epithelial carcinomas of the cervix and endocervical dysplasias. The width and length of the cone can be adapted to the extent of exo- and endocervical lesions. The two main drawbacks of the operation are immediate or delayed haemorrhages and inability to watch the borderline between squamous and cylindrical epithelia, which is no longer visible. These drawbacks are not avoided with the usual technique using invaginating Sturmdorf sutures, whereas conical amputation with a CO2 laser coupled with a hand-piece rather than with a microscope provides virtually bloodless sections and rapid healing, within 3 weeks, without eschar detachment. In addition, there is no risk of secondary stenosis, and the squamous/cylindrical junction remains visible and can be examined by colposcopy, cervicovaginal smears and biopsies.
